Abstract

Objective: A detailed anatomical knowledge of the extensor tendons of the hand is essential for accomplishing successful tendon repair. The aim of this study was to investigate the similarities between the extensor tendon and the thickest intertendinous connections (IC) in the 4th intermetacarpal space, where Type 3 IC is most frequently seen. Methods: A total of 38 dissected hands were studied for anatomical structures that might serve as donor extensor tendons as well as for their relationship with the IC in the fourth intermetacarpal space of the dorsal hand. Results: The most frequent anatomical pattern in the extensor tendons of the fourth intermetacarpal space were the two tendons from the extensor digiti minimi muscle (68.5%) and the thickest type of IC (90%). Other common findings detected at microscopy included the presence of a capsule in the structures associated with the tendon and IC, rich vascularization and high collagen content. Conclusion: Type 3 IC resembles tendons in strength and because of its histological similarity, the IC may be suitable to use in tendon repair. The fourth intermetacarpal space appeared to have the greatest tendon length and thickest IC content and is therefore a suitable donor graft tissue for local tendon repair.

Özet

Amaç: Elin ekstansör tendonlarının anatomisinin ayrıntılı olarak incelenmesi trafik kazaları, kesi ve romatoid artrit gibi farklı nedenlerle ortaya çıkabilecek yaralanmaların başarılı tedavisi açısından önemlidir. Bu çalışmanın amacı, ekstansör tendon ile en kalın connexus intertendinei’nin (CI) benzerliğini, Tip 3 CI’nın en sık görüldüğü dördüncü intermetakarpal aralıkta incelemektir. Çalışma planı: Bu amaçla, 38 elin dorsumunda dördüncü intermetakarpal aralıkta ekstansör tendonların CI ile olan ilişkileri incelendi. Bulgular: Dördüncü intermetakarpal aralıktaki ekstansör tendonların en sık varyasyonu ekstansör digiti minimi kasının iki tendonu (%68.5) ve en kalın CI’nın (%90) bulunması şeklindedir. Mikroskopta rastlanan diğer önemli bir bulgu da, tendon ve CI çevresinde bir kapsülün bulunması, zengin damarlanma varlığı ve yoğun kollajen içeriğidir. Çıkarımlar: Bu bulgular Tip 3 CI’nın gerginlik açısından tendona benzeyebileceği, zaten iki doku arasında histolojik olarak benzer özellikler gözlemlendiği için, CI’nın tendon tamiri için uygun bir doku olabileceğini düşündürmektedir. Dördüncü intermetakarpal aralık en uzun tendonlara ve en kalın IC içeriğine sahip olduğundan lokal tendon tamirinde uygun donör doku olabilir.
